I have the FITech unit on order. $150 rebate + Summit 10% wasn't a bad deal. Should arrive next week. Evidently the Throttle body only flows ~850, which should be OK for me, but might be a deal breaker for a fast guys. Evidently they do not offer much tuning support via the advanced software, and I am a little afraid of what the interface will look like, I have yet to find anyone that has messed with it.
